Question

我有一个关于C的问题，任务是从Char数组创建一个频率字典，我差不多这样做了，但问题是最后，当我尝试将这些字应用到第二个字符数组中时。请提出如何管理此问题的建议。非常感谢。

您的问题出现在以下两行int Computing(...)

中

    NewArray[size]=new T[strlen(Array[size])+1];
    strcpy_s(NewArray[size],strlen(Array[size])+1,Array[size]);

您的Array索引应该是i，而不是size：

    NewArray[size]=new T[strlen(Array[i])+1];
    strcpy_s(NewArray[size],strlen(Array[i])+1,Array[i]);

否则，当i不再等于size时，一旦您开始跳过重复的字词，事情就会开始出错。

正如其他人所说，使用C ++数据结构而不是普通数组会更容易。
